<pre class="docs-method-signature"><code>graph.getCommonAncestor(...cells)</code></pre>
<p>Return the common ancestor of all the cells passed as arguments. For example, if an element <code>B</code> is embedded in an element <code>A</code> and an element <code>C</code> is also embedded in the element <code>A</code>, <code>graph.getCommonAncestor(B, C)</code> returns the element <code>A</code>. This also works on an arbitrary deep hierarchy.</p>
